Introduction: Use winform code is executed after a trigger event, if time-consuming very long, it will result in suspended animation window interface! I recently through the implementation of a winform form: batch update tasks when necessary operating data of a number of databases, since the amount of data to reach one million level, time-consuming, updating only slowly, slowly executed.
However, during the execution of a wonderful experience problems: the form in debug mode, code can be executed cyclically slowly, did not appear abnormal. But when I run alone EXE program, he will now: program suspended animation, not responding state.
Background Although Baidu did not find a direct answer, but also found the reason: because when very time-consuming operation, the program will be suspended animation, the solution is simple: In your time-consuming method where, with asynchronous processing, do not let the program you have been waiting for the results.
The following code:
By asynchronous Task.Run way for a quick end to the method, not the middle of the update process stage operation is the time-consuming, after the adoption of this transformation, the interface is no longer stuck a perfect solution.
